DATALOGIC DS1 SERIES Current Sensing Switch

Product Information

Specifications

• Model: DS1 SERIES
• Receiver (RX) LED Indicators:
  • CONTROLS OUT LED: Yellow LED that indicates the presence of an object in the controlled area.
  • POWER ON LED: Green LED that indicates optimal device functioning. Fast blinking indicates critical device alignment.
• Emitter (TX) LED Indicators:
  • POWER ON LED: Green LED that indicates correct device functioning.
• Installation Modes:

Place the sensitive sides of the units facing each other in a parallel manner with connectors oriented on the same side. Critical alignment is indicated by the fast blinking of the RX green LED.
  • Mounting: Use rigid supports and specific fixing brackets or holes on the device lids to mount the RX and TX units. Avoid strong vibrations.
• Precautions:
  • Choose the device based on minimum object detection and maximum controlled area.
  • In agroindustrial applications, verify the compatibility of light grid housing material with chemical agents used in the production process with the DATALOGIC technical sales support department.
  • The AREAscanTM light grids are not safety devices and should not be used for the safety control of machines.
  • Avoid installation near intense or blinking light sources, especially near the receiver unit.
  • Strong electromagnetic disturbances can affect the correct functioning of the device.
• Object Detection and Measurement:
  • For correct detection and measurement, objects must completely pass through the controlled area. It is suggested to test detection before beginning the process.
• Connections:
  • Receiver (RX): M12 5-pole connector with Analog output, Switching output, and SYNC (TX) connections.
  • Emitter (TX): M12 4-pole connector with +24 Vdc, 0V, SYNC connections.
  • Shielded cables are not included in the standard connection.
  • Ground connection of the two units is not necessary.
  • Use the same power supply for both TX and RX units with a common voltage reference of 0V for correct functioning.
• Functioning and Performances:
  • The passage of an object inside the controlled area causes beam interruption, which results in the closing of the switching output and variation of the device’s analog output signal.
  • The device can detect small objects with dimensions as small as 5 mm and provide linear measurements with a 3 mm error in best cases.
  • The switching output is always activated when at least one beam is obscured. This status variation is indicated by the yellow receiver LED turning on.

INSTALLATION MODES

General information on device positioning

• Align the two receivers (RX) and emitter (TX) units, verifying that their distance is inside the device operating distance, in a parallel manner, placing the sensitive sides one in front of the other, with the connectors oriented on the same side. The critical alignment of the unit will be signalled by the fast blinking of the green receiver LED.
• Mount the receiver and emitter units on rigid supports which are not subject to strong vibrations, using specific fixing brackets and /or the holes present on the device lids.

Precautions to respect when choosing and installing the device

• Choose the device according to the minimum object to detect and the maximum controlled area requested (= operating distance x controlled height);
• In agroindustrial applications, the compatibility of light grid housing material and any chemical agents used in the production process has to be verified with the assistance of the DATALOGIC technical sales support department;
• The AREAscanTM light grids are NOT safety devices, and so MUST NOT be used in the safety control of the machines where installed.

Moreover the following points have to be considered:

• avoid installation near very intense and/or blinking light sources, in particular near to the receiver unit;
• the presence of strong electromagnetic disturbances can condition the correct functioning of the device; this condition has to be carefully evaluated and checked with the DATALOGIC technical sales support department;
• the presence of smoke, fog and suspended dust in the working environment can reduce the operating distance of the device;
• strong and frequent temperature variations, with very low peak temperatures, can generate a thin condensation layer on the surfaces of the optics, compromising the correct functioning of the device;
• reflecting surfaces near the luminous beam of the AREAscanTM device (above, under or lateral) can cause passive reflections able to compromise object detection inside the controlled area.

If different devices have to be installed in adjacent areas, the emitter of one unit must not interfere with the receiver of the other unit.

General information relative to object detection and measurement
For correct object detection and/or measurement, the object has to pass completely through the controlled area; testing the correct detection before beginning the process is suggested.

CONNECTIONS

• Shielded cables are not foreseen in the standard connection
• Ground connection of the two units is not necessary
• Use the same power supply for both units: for a correct functioning both units TX and RX must have the same voltage reference 0V

FUNCTIONING AND PERFORMANCES

• The beam interruption due to the passage of an object inside the controlled area caused the closing of the switching output and the variation of the device’s analogue output signal.
• Small objects can be detected (reaching dimensions of only 5 mm) and determine linear measurements with a ±3 mm error in best cases.
• In particular, the switching output is always activated when at least one beam is obscured. The status variation is signalled by the yellow receiver LED that turns on.
• The analogue output value (0-10 V) is proportional to the number of obscured beams (0V means that no beam is interrupted, and 10V all beams are interrupted)
• The device does not require calibration; periodical checks of the resolution and/or measurement are however suggested.
• The blinking of the green receiver LED (stability function) signals the critical alignment of the units and/or the functioning outside or near the maximum operating distance. In optimal conditions, the LED remains on continuously.
• The two units are synchronised via cable (SYNC wire); precarious connections or induced disturbances on the synchronism line can cause device malfunction or temporary blocking.
• The diagrams, given below, show the typical minimum resolution trend of each model, SR (standard resolution) and HR (high resolution), according to the operating distance (D). For DS1-LD-SR-XXX-PV, the minimum resolution at a particular operating distance is to be intended with the trimmer calibrated near the commutation threshold for that distance.

EMISSION POWER REGULATION

EMISSION POWER REGULATION (only DS1-LD-SR-XXX-PV)
The emitter is equipped with a trimmer which lets the user change the emission power. The operating distance increases rotating the trimmer clockwise. The emission power reduction is useful to decrease passive reflections when the maximum operating distance is not required. Trimmer rotation is limited to 260°. Do not apply a torque greater than 35 Nmm.

Rotate the trimmer clockwise to the limit (maximum emission), then align RX and TX at the required operating distance (LED OUT off); decrease emission power by rotating the trimmer counterclockwise until the output switches (LED OUT off) or the limit is reached (minimum emission); in the first case, rotate the trimmer clockwise until the output switches again and LED OUT remains off.
